SHUTTLE-MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 714,169, dated November 25, 1902.

Application filed August 17, 1901. Serial No. 72,406. (No model.)

To all whom it may concern:

Be it known that l, JOSEPH A. GENDRON, a citizen of the United States, and a resident of Nashua, county of Hillsboro, State of New Hampshire, have invented certain new and useful Improvements in Looms, of which the following is a full, clear, and exact description.

The object of my invention is to produce a loom having features of novelty and advantage over those now in use, and has particular reference to the shuttle-carrier and its operating mechanism.

Figure 1 is a front elevation of the loom in which my invention is embodied. Fig. 2 is a top view of the shuttle-carrier in section,

showing one position of the gripping-fingers.-

Fig. 3 is a similar view to Fig. 2, butshowing the other position of the gripping-fingers. Fig. 4 is a side sectional view of the carrier. Figs. 5 and 6 are side sectional views of the carrier, showing details of the construction.

Referring to the drawings, A denotes the frame of a loom, and B denotes the lay-fram e, which is pivoted in the loom-frame and is of the ordinary construction, adapted to swing in one direction while the warp-threads are separated or shed to permit a passage of the shuttle and in the opposite direction to lay the weft-thread in each passage of the shuttle through the warp. The power-shaft O,which drives the moving parts of the loom, is mounted on the loom-frame, asat D, and is connected by a link with the lay-frame, so that as the shaft revolves it will impart an oscillating movement to the lay-frame, this connection being arranged to move the lay-frame in one direction to part the warp-threads and permit the shuttle to pass through and then to move the lay-frame in the opposite direction to lay the thread which has been passed through the warp by the shuttle on the top of the lay-frame. At each end I mount what may be called shuttle-carriers E F, which control the movement of the shuttle to and fro through the warp-threads. These carriers have a limited movement toward and away from each other, which movement is controlled by the levers G, pivoted at their lower ends to the lay-frame and having lugs H projecting therefrom, which work in camslots (1 in stationary plates I, which are sotle and remove it from the jaws of the other carrier, whose grip on the shuttle has been automatically released.

The carrier and its operation are shown clearly in Figs. 2, 3, 4, 5, and 6. 1 denotes the body of the carrier F, having the mortise 2 extending through it and pierced lengthwise, as at 8, to receive the plunger 4. This plunger is headed at one end 5, and the spring 6encircles it between the head and the bottom of the socket 7. The rearend of the plunger has two projections 8 9 and the spring-catch 10. Pivoted to the front end of the carrier-bodyare the arms 11 12, having fingers 13 14 projecting in front of the body, the rear ends of the arms being bent in, as clearly shown at 15 16, Figs. 4 and 5. When the carrier is empty, the parts will occupy the positions shown in Fig. 4, the arms 11 12 lying closely against the body of the carrier. WVhen this carrier moves up to take the shuttle, the fingers 13 14 lie on each side of the shuttle and its point engages the head of the plunger, forcing it back, as shown in Fig. 3. This movement of the plunger throws out the arms 11 12 and throws the fingers 13 14 against the shuttle to firmly grasp it. Fig. 4 shows in side View the position of the parts as they appear in Fig. 2, and Fig. 5 shows in side view the position of the parts as they appear in Fig. 3, showing the spring-catch 1O engaging the rear end of the carrier-body to hold the plunger back. Pivoted to the lower part of the body is the sleeve 17, which carries the rod 18, having at one end a pivoted dog 18 to permit of its riding over the tripping-lug 22 on the return movement of the carrier. This rod is capable of a movement through the sleeve 17 and is held in this normal position in Fig. 4 by means of a spring 19. This sleeve is connected with the plunger 4:, as by the bale 20, and when the plunger is in its forward position, as shown in Fig. 4, the sleeve and the rod 18 will occupy the positions shown as the carrier begins its forward movement. At the time the carrier F reaches the limit of its forward movement and the shuttle is gripped by both the carriers, as shown in Fig. 6, the pivoted dog at the end of the rod 18 comes in contact with a tripping-lug 22, which forces the rod backward through the sleeve, releasing the springcatch 10 from its engagement with the rear end of the carrier-body, as is clearly shown in Fig. 6. This permits the plunger to move forward under the impulse of a spring 6 and permits the arms 11 12 to resume the positions shown in Fig. 2, releasing the grip of the fingers 13 14 on the shuttle. A spring 23 may be wound around the pivot of these arms, as shown in Fig. 2, to throw the fingers 13 14 apart when the plunger is released. Two shuttles of this construction maybe used in a loom, although it is only necessary to use one of this construction; but in the drawings in Fig. 1 I have shown onlyone of these carriers F, the opposite carrier E being simply a plain body withapairof gripping-fingers. The carrier F needs some firm grip to withdraw the shuttle from the fingers of the carrier E; but inasmuch as the grip of the fingers 13 14 of the carrier F is released the spring of the fingers of the carrier E is su fficient to take the shuttle from F. In ordinary looms when the thread breaks or is spent the end is drawn partly through the warp and leaves a bunch or knot or an uneven surface, which makes it neces sary to put that piece of cloth in as second at a considerable loss. To both of the carriers in my improved loom I attach a clip 25. While the loom is running normally the thread as it comes from the shuttle passes through this clip, as shown at 25 in Fig. 3. When the thread breaks or runs out, this clip holds it with enough of a grip to carry the end out of the warp. Abrush 25 is fixedly mounted on the frame, so as to brush out of this clip on its return or outward movement the end of thread which has been withdrawn from the Warp. .It will be seen from this that the shuttle is carried from one side of the loom and delivered to the other carrier, which continues its movement through the warp, and then the second carrier carries it in until it is taken by the first-named carrier.

By arranging the loom in this manner and controlling the movement of the shuttle by the carriers above described I provide what is practically a noiseless loom having none of the rattle and clash of all looms as they are now built. This is an important feature of the invention.

I claim as my improvement 1. In a machine of the class specified, the shuttle, the shuttle-carrier, and a thread-clip arranged on the shuttle-carrier, as and for the purposes specified.

2. In a loom, in combination, the frame, the lay-frame pivotally mounted therein, carriers for controlling the movement of the shuttle, and means for imparting motion to said carriers, of a clip arranged on the shuttle-carrier and a brush fixedly mounted on the layframe in operative relation to said clip.

3. A shuttle-carrier for looms and like machines comprising a body portion, arms pivotally attached thereto at a point between their ends, said arms projecting at the front of the shuttle-carrier in the form of springfingers, means cooperating with the rear ends of said arms and actuated by the shuttle for moving the fingers towardeach other to grip the shuttle, substantially as described.

4:. A shuttle-carrier for looms and like machines, com prising the body portion, arms pivotally attached thereto and extending beyond the front of the body in the form of springfingers, a plunger adapted to be operated by the shuttle to move the fingers toward each other, and a spring-catch for the plunger.

5. A shuttle-carrier for looms and like machines,comprising the body portion, arms pivotally attached thereto and extending beyond the front of the body in the form of springfingers, a plunger adapted to be operated by the shuttle to move the fingers toward each other, a spring-catch for the plunger, and a releasing device for said catch.

6. The combination in a shuttle-carrier with the body, the arms pivotally attached thereto and extending beyond one end thereof in the form of spring-fingers, a plunger for moving said arms, and a clip secured to said carrier and adapted to hold the thread as the shuttle passes through the warp.
